ENGINEERING OVERVIEW

Candidate decision overview

Data version 3

GEOMETRY CONTRACT

Conical profile

Bearing surfaces: No
Tolerance grade: See dossier / confirm

Special surface parameters must be reviewed against the released drawing; the profile name alone is not a complete geometry definition.

EVIDENCE COVERAGE

✓Manufacturer curve / stress2✓Polysplendid calculations1✓Resolved standards2✓Inspection dossier1—Approved product FEMNot public

A missing FEM record is not evidence of failed validation. It means no approved product-level study is public on this page.

COMBINATION BOUNDARY

Check single disc before stack

Parallel stacks primarily multiply load; series stacks primarily multiply travel. Friction, contact, guidance, preload and manufacturing scatter must be checked separately.

APPROVED SOURCE DATA

Manufacturer engineering data

2 traceable datasets

Loads, stresses, thousand-piece weights and curves retain their manufacturer, source version, page/worksheet, material and temperature condition. A catalog value is an engineering reference unless the inspection dossier separately identifies an approved acceptance tolerance.
